Electrochemistry Using Nanometer-Sized Electrodes

Abstract

Electrodes with dimensions as small as 10 A have been fabricated and used for electrochemical studies. Remarkably large current densities are generated by these ultra small electrodes, as predicted by conventional radial diffusion theory. These large current densities have enabled the measurement of electron transfer rate constants, k sub het, which are two orders of magnitude faster than k sub het values accessible using any other electrochemical method. Keywords: Ultramicroelectrode, Nanode, Heterogeneous electron transfer rate, Steady state, Kinetics.
